J. VAN HORNE, OF MAGNOLIA, ILLINOIS.

GRAIN-SEPARATOR.

Specification of Letters Patent No. 13,532, dated September 4, 1855.

To all whom it may concern:

Be it known that I, J. VAN HORNE, of Magnolia, in the county of Putnamand State of Illinois, have invented a new and Improved Machine forShelling Corn from the Cobs; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the annexed drawings, making a part of this specification, in which-Figure 1, is a longitudinal vertical section of my improvement 00, m,Fig. 3, showing the plane of section. Fig. 2, is a transverse verticalsection of ditto, y, 3 Fig. 1, showing the plane of section. Fig. 3, isa plan or top view of ditto.

Similar letters of reference indicate corresponding parts in the severalfigures.

The nature of my improvement in corn shelling and cleaning machines,consists in furnishing a revolving cylinder or shell (placed exteriorlyto a revolving screen) with a series of revolving cups or buckets placedupon its exterior, said cups in their revolution passing through asuitable trough placed below the cylinder, into which the shelled cornis dropped through holes in the cylinder having been conveyed to theseholes by spirally placed flanges, situated on the interior of thecylinder. By this means the grain is separated and elevated to an upperdelivery spout to which the bag for receiving the grain may be attached,while the cobs received with the grain from the thresher into therevolving wire screen will be delivered at the end of the machine. By myinvent-ion I dispensewith the necessity of having separate elevators anddriving gear &c. and thus reduce the cost of construction and greatlyenhance the etficiency of the machine.

To enable others skilled in the art to fully understand and construct myinvention I will proceed to describe it.

A represents the framing of the machine, which may be of rectangularform, and B, represents a cylinder placed transversely on the front orfeeding end of the machine.

Directly underneath the cylinder 13, there is placed a corrugatedconcave C, see Fig. 1. This concave may be formed of cast iron. On theperiphery of the cylinder B, there are oblique ribs or project-ions, a,the form of which is clearly shown in Fig. 3. These ribs or projectionsextend obliquely from the ends of the cylinder to its center where theyform a point or angle at 5, each rib or projection being of somewhat V-form.

D, represents a feed board placed at the front end of the framing A.This board is somewhat inclined and its inner end is secured to theouter end of the concave C, as clearly shown in Fig. 1.

In the back end of the framing A, there is placed a cylinder E. Thiscylinder is fitted between friction rollers, c, at its front and backends, as shown in Fig. 1, the friction rollers being attached to theframing i Around the center of the cylinder E, on its outer side thereare placed a series of buckets, d. These buckets are placed be tweenflanges e, e, which surround the cylinder and are concentric with thebuckets. The outer edges of the flanges incline in.- ward or toward eachother, and holes f, are made through the cylinder underneath the flangesand at each side of the buckets, as clearly shown in Fig. 1. On theinner side of the cylinder E, there are attached spiral flanges, g, ateach side of the holes, f, these flanges extend from the ends of thecylinder to the holes, f, and the spiral curves of the flanges on oneside of the holes are in a reverse position to those on the other side.

Within the cylinder E,there is secured a cylindrical screen F, which issomewhat smaller in diameter than the cylinder so as to leave a spacebetween the cylinder and screen, as shown in Figs. 1 and 2. The screenhas spiral toothed flanges g, on its inner surface also shown in Figs. 1and 2.

G, is an inclined spout which leads from the inner end of the concave C,to the in terior of the screen F.

At the lower part of the framing A, there is placed a fan box H, whichhas a blast spout I, attached to it, said blast spout communicating withthe inner ends of the cylinder E, and screen F, as shown in Fig. 1. Thebox II, has a rotary fan H, within it. Around the inner end of thecylinder E, there is placed or attached teeth h, see Fig. 3, in which apinion J, gears, said pinion being attached to the inner end of smallshaft K, which works in suitable bearings in the framing A. To the outerside of the shaft K, there is attached a pulley L, around which a beltM, passes, said belt also passing around a pulley N, at one end of theshaft of the cylinder B; O, is a cross belt which passes around pulleysP, Q, at the ends of the shaft of the cylinder B, and the end of theshaft of the fan H. The driving pulley R, is attached to the oppositeend of the shaft of the cylinder B.

The framing A, may be inclosed with proper sides, and boXes or covers,71, may be placed over the top of the framing.

Operation: Motion being given the driving pulley R, in any proper mannerthe cylinder B, fan H, and cylinder E, and screen F, rotate, the ears ofcorn are thrown upon the inclined feed board D, and pass down betweenthe cylinder B, and corrugated concave C, and the corn is shelled fromthe cobs and in consequence of the oblique position of the ribs orprojections, a, on the cylinder B, the shelled corn and cobs will becarried up to the inclined spout G, and discharged from between thecylinder and concave at the center of the cylinder. The shelled corn andcobs will be discharged from a single point without being at allscattered and will pass down the spout G, into the screen F, throughwhich a blast generated by the fan H, passes. As the screen F, rotatesthe cobs will be carried by the spiral toothed flanges, g, to the outerend of the screen F, and will be discharged therefrom, while the shelledcorn will pass through the screen and fall upon the inner side of thecylinder E, and will be conveyed by the flanges, g, to the holes, f,through which the corn passes into the buckets, d, and is carried aroundby them and discharged from the side of the framing, as shown in Fig. 2.Thus it will be seen that the corn is shelled from the cob and the cornand cobs discharged at separate points from the machine, the corn beingalso winnowed or cleansed from dirt at one operation. If the screen F,is slightly in clined the cobs may pass out of the screen without theaid of the spiral flanges, g. I prefer however the flanges which renderthe ejection of the cobs certain.

I claim- The revolving cylinder E furnished with buckets cl, flanges g,and holes f, in combination with the revolving cylindrical screen F,constructed substantially as described for the purpose of cleaning thegrain, separating the cob and elevating the grain and delivering it inthe manner substantially as set forth in the foregoing specification.
